An Application of Multimedia Services on Transportation: The Use of the World Wide Web (WWW)
INTRODUCTION
In recent years, there is an ever-increasing demand and interest in the use of multimedia
technology and applications in industry, government and academia. Multimedia is often
seen by researchers as the next step forward in interfacing science, technology and
community. Yet, the terminology of multimedia bears several meanings. It may refer to
Compact Disc (CD), moving pictures or video-conferencing. The multimedia technology
referred in this paper is the World Wide Web (WWW) hypertext publishing information
system which was developed by and started at the European Laboratory for Particle
Physics (CERN) in Geneva, Switzerland. Since the introduction of WWW, its use has
increased dramatically within a couple of years in a widely diverse community including
government departments, university and research establishments, and commercial
organisations. It has significant influence to our communities and our daily lives. Yet, in
most cases, applications of WWW services are largely restricted to electronic library
referencelcatalogue search facilities, electronic mail systems, electronic conference and
discussion systems, electronic news and publishing agents, and remote access to computing
resources on the Internet.
The primary objective of this paper is to exploit the potential of this multimedia technology
as a simple, easy-to-use and effective means of telematics application in transportation
research. It is hoped that initiatives are highlighted via this study and hence encourage
participations and collaborations from different sectors of industries.
In this paper, a brief history of WWW is given in section (2). An overview of the technical
aspects in providing a WWW service is presented in section (3) in terms of computer
hardware requirements, software installation, network connections, application
maintenance and administration, and system security. Compared to most commercially
available multimedia software in the market, WWW services are cheap to run, userfriendly
and readily available to the public on the Internet. In order to exploit the potential
of WWW on transportation research, a study was carried out and results of the findings are
reported in section (4). To further substantiate the level of usefulness, two particular
WWW applications were chosen amongst other web services and they are reported in
section (5) for illustrative purposes. The selected applications are the 'Transportation
Resources on the Internet' developed in mid-1994 in the Institute for Transport Studies
(ITS) at the University of Leeds in England, and the 'Southern California Real-Time
Traffic Report' developed by Maxwell Laboratories, Inc. in collaboration with the
California State Department of Transportation in the US. Finally, a set of issues are raised
in section (6), highlighting the directions of future development of WWW as an easy-touse,
cheap and effective multimedia telematics application on transportation
Durkheim's imperative: The role of Humanities faculty in the information technologies revolution
The arrival of powerful information technologies in the traditional
humanistic disciplines has done far more than simply add to the tools
available for research and instruction. Those who have embraced these
technologies have also experienced a significant disruption of their
traditional roles within the academy, producing confusion and
disorientation as well as excitement and innovation. Some of the reasons
for this confusion are discussed, and one example of two "restabilized"
roles for humanities faculty the work of the Advanced Information
Technologies Group at the University of Illinois is described. The
conclusion explores some of the advantages of this new kind of division
of intellectual labor.published or submitted for publicatio
World Wide Web Implementation of the Langley Technical Report Server
On January 14, 1993, NASA Langley Research Center (LaRC) made approximately 130 formal, \u27unclassified, unlimited\u27 technical reports available via the anonymous FTP Langley Technical Report Server (LTRS). LaRC was the first organization to provide a significant number of aerospace technical reports for open electronic dissemination. LTRS has been successful in its first 18 months of operation, with over 11,000 reports distributed and has helped lay the foundation for electronic document distribution for NASA. The availability of World Wide Web (WWW) technology has revolutionized the Internet-based information community. This paper describes the transition of LTRS from a centralized FTP site to a distributed data model using the WWW, and suggests how the general model for LTRS can be applied to other similar systems

Accessing NASA Technology with the World Wide Web
NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experi..
Long Duration Exposure Facility (LDEF) Archive System
The Long Duration Exposure Facility (LDEF) Archive System is designed to provide spacecraft designers and space environment researchers single point access to all available resources from LDEF. These include data, micrographs, photographs, technical reports, papers, hardware and test specimens, as well as technical expertise. Further, the LDEF Archive System is planned such that it could be the foundation for a NASA Space Environments and Effects (SEE) Archive System, with the addition of other spaceflight, laboratory and theoretical space environments and effects data and associated materials. This paper describes the current status and plans of the LDEF Archive System
Back from the brink: Microsoft and the strategic use of standards in the Browser Wars
The browser wars are probably the best-chronicled standards competition in recent history. Yet the standard lock-in model does not readily account for the dramatic change in fortunes of Microsoft. At one time it seemed that Microsoft would be go the way of IBM before it and fail to catch the next technological wave in the computer industry. However Microsoft managed to capture the browser market, overturning Netscape''s initial domination of the market. In seeking to understand this dramatic return of events, the paper begins by outlining the key elements of the Arthur model. This is followed by a historical narrative of the browser wars that highlights three aspects of this technological competition; firms'' strategic use of standards, users'' considerations of initial set-up costs, and the degree of interconnectivity between product markets. The paper finally considers how the standard lock-in model may be extended in order to encompass these dimensions.economics of technology ;
Results from the First World-Wide Web Survey
The explosion of World-Wide Web (WWW) across the Internet is staggering, both in terms of number of users and the amount of activity. However, to date, no reliable characterization exists of WWW users. In this paper, we report results from a survey that was posted on the Web for a month, in January of 1994. There were several goals motivating our survey. First, we wished to demonstrate a proof of concept for WWW technologies as a useful survey medium. Second, we wanted to bet a-test the design and content of surveys dealing with the Web. Third, as mentioned, we hoped to begin to describe the ra nge of Web users. In one month, we had over 4,700 respondents to our survey. Their responses helped us to begin to characterize WWW users, their reasons for using the WWW, and their opinions of WWW tools and technologies
A Strategy for Electronic Dissemination of NASA Langley Technical Publications
To demonstrate NASA Langley Research Center\u27s relevance and to transfer technology to external customers in a timely and efficient manner, Langley has formed a working group to study and recommend a course of action for the electronic dissemination of technical reports (EDTR). The working group identified electronic report requirements (e.g., accessibility, file format, search requirements) of customers in U.S. industry through numerous site visits and personal contacts. Internal surveys were also used to determine commonalities in document preparation methods. From these surveys, a set of requirements for an electronic dissemination system was developed. Two candidate systems were identified and evaluated against the set of requirements: the Full-Text Electronic Documents System (FEDS), which is a full-text retrieval system based on the commercial document management package Interleaf, and the Langley Technical Report Server (LTRS), which is a Langley-developed system based on the publicly available World Wide Web (WWW) software system. Factors that led to the selection of LTRS as the vehicle for electronic dissemination included searching and viewing capability, current system operability, and client software availability for multiple platforms at no cost to industry. This report includes the survey results, evaluations, a description of the LTRS architecture, recommended policy statement, and suggestions for future implementations
